제목 Neuronal differentiation of adult bone marrow stromal cells using SIS sponges.
초록 Bone marrow stromal cells (MSCs) are multipotent stem cells that can be differentiated into mesenchymal cell types such as chondrocytes, osteoblasts, adipocytes, and muscle cells by controlling cytokines in culture medium1,2.
Small Intestinal submucosa(SIS) is an acellular biomaterials and consists of naturally occurring ECM that has been shown to be rich in components which support regeneration of tissue such as fibronectin, glycosaminoglycans including heparin, several collagens including types Ⅰ, Ⅲ, Ⅳ, Ⅴ, and Ⅵ, and growth factors such as b-FGF, TGF-β, and VEGF. So, it is to be important for tissue regeneration3,4.
In this study, adult rat bone marrow stromal cells can be induced to overcome their mesenchymal commitment and differentiate into neurons in SIS sponge, potentially their usefulness in the treatment of neuronal disease. In vitro, MSCs were seeded in SIS sponges for 14 days. The neurogenesis of MSCs culture was assessed by histology, RT-PCR, SEM, and MTT assay. In histological analysis, we confirmed that neurogenic differentiated rat MSCs expressed NSE and NF.
